Well finally got a response from expertflyer:

Hi, thank you for your email. We sincerely apologize for the recent inconvenience caused by a system error that led to a mass amount of alerts being sent out. Our team had to switch to a new database, which then caused this glitch. You may see alerts that have a six-hour difference, you may see alerts that have expired, and you may see alerts that were previously deleted. We advise you to double-check existing alerts you have to ensure they are entered (and showing) correctly. If they are not showing the correct information, please resubmit them. Thank you for your continued support and patience.
Thank you,
The ExpertFlyer.com Team "
